Hey Cat. I would consider trading the puzzle for another puzzle or selling as a pair but probably wouldn't break them up since the Nova only really works as part of the battle and not a stand alone.
haha to me these are kind of middle ground. I actually dont mind the art too much, just the characters are not of massive appeal to me. The Nova with the back turned is indeed a short cut though i agree.
For me the Glebes are the absolute best in the business. The only other i would up there is NAR! but considering he isnt on many sets, the Glebes get my vote.
